PK - Polyketone

Semi-crystalline thermoplastic

The material's special characteristics fulfil the high requirements of various application areas. It allows for components to be used in areas with high mechanical, tribological and chemical requirements at the same time.

Deal for parts subject to continuous dynamic stress and high load alternation, such as gear wheels or friction bearings.

Its low water absorption rate of 0.4 % in an average climate allows for its use in environments where parts may come in contact with moisture - for instance cable guides used for ship building and off-shore applications.

Special properties

  • Very good resilience
  • Low moisture absorption
  • Very high abrasion resistance
  • High impact strength
  • the wear rate is incredibly low in comparison with other polymers when it is used with friction partners made of the same material
  • remains accurate to size and retains its dimensional stability

Typical areas of application

  • Mechanical engineering
  • Seals
  • Aircraft construction
  • Ship building
  • Offshore
